Question

Whats wrong with these pre-processor directive in C#

#define OUTPUT_DIRECTORY "E:asdfsdfgjhkl"

I also tried giving:

#define OUTPUT_DIRECTORY "E:\asdf\sdfg\jhkl"

for both I get error:

Error 1 Single-line comment or end-of-line expected

Answer 1

You cannot give that symbol (OUTPUT_DIRECTORY) a value, the symbol can only be "defined" or "undefined" so you can use it in a #if OUTPUT_DIRECTORY ... #endif.
